That confirms my ideas about how it should work. Even without partitioning, you can define two libraries, that are both controlled by the same control-path (device node in unix). That may be a workaround for this issue? I see no real downsides to that solution, though I agree that TSM should only mount tapes that are actually compatible with the format you have set in the device class.
